Figure 2.

Heating behavior of uncoated and lipid-coated SPIONs within an alternating magnetic
field. Uncoated (open symbols) and lipid-coated (closed symbols) Fe3O4 nanoparticles suspended at 0.02 mg/mL in citrate buffer, pH 7.4, were exposed in
the MGS-1000 to an alternating magnetic field of 7.0 mT at 1.0 MHz (circles) and in
the MHS to 16.6 mT at 13.6 MHz (squares). Temperature of suspension vehicle was recorded
using an optical fiber probe. Data are shown as mean ± SD (n = 3).
